Phono Preamp Reviews

Trickle-down technology is a grand thing. It's comparatively easy to build an exceptional audio component when there are no constraints on technology, cost, user-friendliness, or lack thereof, but top designers are now packing more and more of the excellence of damn-the-torpedoes components into more affordable and accessible packages. Which brings us to the Aesthetix Rhea, a tubed phono preamplifier of exceptionally distinguished lineage.

The catastrophic February 6 fire at the factory where Apollo Masters produced LP-mastering lacquers—flat aluminum discs covered with nitrocellulose lacquer—will be old news by the time this column gets to you, but the repercussions of the loss will be ongoing for at least the next year and probably beyond.

The German company AQVOX Audio Devices has produced an innovative moving-coil/moving-magnet solid-state phono preamplifier, the Phono 2Ci, that's as intriguing for its technology and performance as it is for its relatively low price: $1400. The zero-feedback, op-amp–free circuit uses a compact switch-mode power supply that's built into the chassis and features conventional voltage gain for moving-magnet cartridges via its RCA jacks, and current gain for moving-coil cartridges through the balanced XLR inputs. Rear-panel switches select between RCA or XLR inputs and offer a convenient ground lift. Either the single-ended or the balanced outputs can be used with either input. Unfortunately, the tight spacing of the RCA input and output jacks, which are mounted on the circuit board, will somewhat limit your choice of cables: Pairs of thick-barreled plugs will have difficulty fitting.

"Everybody's gotta get into the act!" Jimmy Durante used to say. That's what's happening with phono preamplifiers—they just keep being built, and I keep getting them for review. Up for evaluation in next month's column are new models from Perreaux, Musical Fidelity, Graham Slee, and a Chinese one, Ming Da. You can bet there'll be more.

Audio Research's long-promised "final statement" phono preamplifier has finally arrived, and its price is $3500 less than the originally rumored $10,000. That's a pleasant deviation from the audiophile norm, but at $6495, the Reference phono still boasts a steep ticket. That's more than twice the price of the $2495 PH3 SE, AR's previous best—a class sonic act itself.

Some of the most innovative thinking on hybrid circuit design these days seems to come from Russian designers. As a group, they are technically very well educated, pragmatic, and unfettered by American high-end didacticism.
